| Summary, etc | Objectives: As a treatment for partial deafness with residual hearing in<br/>the lower frequency range, the combined acoustic and electric stimulation<br/>of the cochlea has become widespread. Acoustic stimulation is<br/>provided by a hearing aid’s airborne sound and the electric stimulation<br/>by a cochlear implant electrode array, which may be inserted through the<br/>round window or a cochleostomy. To take advantage of that concept, it is<br/>essential to preserve residual hearing after surgery. Therefore, the intracochlear<br/>electrode array should not compromise the middle ear vibration<br/>transmission. This study investigates the influence of different electrode<br/>types and insertion paths on the middle ear transfer function and the<br/>inner ear fluid dynamics.<br/>Design: Sound-induced oval and round window net volume velocities<br/>were calculated from vibration measurements with laser vibrometers<br/>on six nonfixated human temporal bones. After baseline measurements<br/>in the “natural” condition, a cochleostomy was drilled and closed with<br/>connective tissue. Then, four different electrode arrays were inserted<br/>through the cochleostomy. Afterwards, they were inserted through the<br/>round window while the cochleostomy was patched again with connective<br/>tissue.<br/>Results: After having drilled a cochleostomy and electrode insertion,<br/>no systematic trends in the changes of oval and round window volume<br/>velocities were observed. Nearly all changes of middle ear transfer functions,<br/>as well as oval and round window volume velocity ratios, were<br/>statistically insignificant.<br/>Conclusions: Intracochlear electrode arrays do not significantly<br/>increase cochlear input impedance immediately after insertion. Any<br/>changes that may occur seem to be independent of electrode array type<br/>and insertion path. |
